To all whom it may concern:

Be it known thatI We, ilVrLLIAM R. STEW- Aur and THOMAS S. S'rinmn'i', citizens of the United States, residing et Saltsburg, in the county o Indiano and State of Pennsylvania, have invented certain new and useful" lnipreveinents in Tires; end We do declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to Which it appertains to malte and use the saine.

Ifhis invention relates to tires, especially. adujo-ted for use on autoniobiles.

The object of the invention is to provide e tire which is strong and durable, and Which has a perfect spring and cushioning effect.

With this and other objects in view, the invention consists of certain novel Jfeatures oi' construction, combination and arrangement oli parts, es will he incre fully escribed and particularly pointed out in the appended. claims.

ln the accompanying drawings: Figure l represents a side elevation partly in section or' e portion of a Wheel with this improved tire applied. Fig. 2 is o. transverse section, taken on line 2-2 of Fig. l. Fig. 8, is

, on line 343 of Fig. l, Fig. l is e side elevation partly in section oi one of the cushioning cylinders, detached, 1rEig. 5 is a side elevation` of the centrally disposed clamping ring, detached.

ln 'the embodiment illustra-ted, the Wheel l .is provided with the usual metallic rim mounted on the felly This metallic rirn i on its opposite i and 5, which entend .outwardly Y,in arallel planes, end forni guides for the casing to be described.

easing is mounted on the tire or riin 2 end comprises two metallic sections 7 and 8, with. outiverdly bulging sides, es clearly shown in 2 and 3, and which are connected together with bolts, as 9, which pass transversely through the casing. These sections 7 and 8 are provided, at their inner ends, With depending flanges 'l0 and ll., which are spaced slightly from the sides of the rim 2, and ere edepted to rnove vertically thereon when the tire is compressed.

A. packing 12 preferably arranged between the sides of the rim 2 and-the flanges l() and il, and is mounted in grooves i3, formed in each side of the rim 2, as is clearly shown in Figs., 2 and. 3. The outer portion of the casing formed by sections 7 and 8, is provided With outwardlyextending, perallel ionges 14 and l5, arranged at opposite sides of the casing, end between which on the lateral flanges 14 and 15 which project inwardly to form the periphery of said casing is mounted the ordinary rubber tread or tire 16, which may be secured thereto in any-suitable or desired manner. irrenged Within ,the casing 6 are a plurality of spring members 17, each preferably made in the form of a rubber cylinder having peripheral grooves, as 18, at its opposite ends, and a groove 1Q et the center thereof. These grooves are designed to receive inetallic securing bands 20., 2l and 22, which are clearly shown in Fig. 1. The bands 2O and 2i, which pass erouhd the ends of the cylinder and are arranged in the grooves 18, are provided with laterally extending ends, as 23,Whieh ere preferably made angular and are adapted to extend into apertures 24 formed in the outer rirn which is formed by the periphery of the easing 6. The band 22 which is mounted in the groove 19 of the cylinder 17 is provided with overlap ping ends,'through which a pin 25 passes. This pin is preferably made screw/threaded et its opposite ends and one end thereof extends into e screw-threaded aperture formed in the rim 2 and its other end engages :in aperture in the band 22 diainetrically opposite its overlapped ends, and which securely holds the cylinder in position. The pins 9, which pass transversely through the casing 6,' also pass through the bands 20 and 2l und through the ends of the cylinder 17.

It will be evident from the construction shown that pressure exerted on the tread 16 oil the tire Will ceusethe casing 6 to move inwardly on the guide flanges 4: and 5 of the' rim 2, and the rubber cylinders will give a perfect cushioning eii'ect thereto From the foregoing description, taken in connection'vvith the accompanying drawings, the cnstruction andv operation of the invention will be readily understood Without requiring a more extended explanation.

i Various changes inthe form, proportion s a tread member secured to the and the minor details of construct-ion may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined in the appended claims.

We claim as our invention: y

1. A vehicle tire comprising a hollow,`annular, metallic casing having outwardly bulged sides and provlded with spaced, depending flanges at the inner face thereof, adapted to embrace the sides of a Wheel rim, periphery of said casing, a plurality of rubber cylinders arranged longitudinally within said casing, and secured thereto.

2. A vehicle tire comprising a4 hollow, an nular, metallic casing having outwardly bulged sides and provided with spaced, depending langes-at the inner face thereof, adapted to embrace the sides of a wheel rim, a tread member secured to the periphery of said casing. a plurality of rubber cylinders arranged longitudinally Within said casing, means for securing said cylinders to said said rim, a packing arranged between said fianges and said wheel rim, a plurality of cushioning cylinders arranged Within said casing, bands extending around the opposite ends of said cylinders and havin means for connection with the casing an bands extending around the centers of said cylinders, and provided with means for engaging the wheel rim.

In testimony whereof we have hereunto set our hands in presence of two subscribing Witnesses.
